Greenhouses
Imperial Builders & Supply built their first double poly and steel greenhouses in the 1970s and have since built hundreds of ranges throughout Florida and the Southeast.
Designs
Our “Grand” Greenhouse designs have been engineered to meet the demands for increased wind loads and taller greenhouses. Significant improvements have been made to enhance strength, longevity and versatility. These designs are also easier to erect, allowing nursery owners the option of building their own greenhouses.
